Pull request overview

This PR introduces automation to generate an extension-build test matrix and to analyze PR changes/labels for driving CI test selection, while also improving download robustness and adjusting several package/build behaviors.

Changes:

• Add dev:gen-ext-test-matrix and dev:test-bot commands, and wire them into the console app and CI workflow for label-gated extension test runs.
• Add retry support to GitHub/cURL/git download paths and adjust binary extraction to support merging into the shared buildroot.
• Update multiple package configs/build scripts (curl deps, zstd libs, assorted extension patches, docs updates, etc.).
